How is it going? My trailblazer started making a deep "wooo" sound about a week ago togaether with vibration on the gas pedal. I have about 88000 miles on it. Itgoes louder as I accelerate up until about 40 mph and then it gets a little quiter as I keep accelerating but can still hear it doesnt matter if its is on D or 3 or 2 it is still the same noise. It sound slike its coming from the passenger wheel side. I tried the turning left to see if it sound more on the right and viceversa but can't notice any difference. Does anyone has any suggestions. I was told that it mught be the wheel bearings.
